"What I know is when the racing is tighter and there's more passing, there's just more excitement and more contact and more things that happen," France said in an interview with ESPN.com. "That's kind of what NASCAR is all about.

"Kind of what happened on Sunday was a prototype event for how we would look (or) what a good event ought to look like."

Hamlin and Joey Logano bumped and banged and finally crashed while racing for the lead on the final lap at Auto Club Speedway. Hamlin, whose car slammed nose-first into the inside retaining wall, suffered a compression fracture to a vertebrae in his lower back and will miss at least the next five races.

Kyle Busch charged past Logano and Hamlin to win the race. An angry Tony Stewart went after Logano after the race, shoving him and taking a swing at him for blocking him on the final restart.

Stewart then ripped Logano in a profanity-laced TV interview afterward, calling him a “Dumb little son-of-a-(expletive) ...” and threatening to “bust his ass.”

Logano and Hamlin were racing for the lead a week after having their own problems at Bristol, where Hamlin spun Logano and Logano confronted him on pit road after the race.

NASCAR officials said they had no problems with the way Logano and Hamlin raced each other on the final lap at California and issued no fines to either Logano or Stewart.

France told ESPN.com that he had no plans to talk to Logano and Hamlin about their budding feud.

France said the battle between the two drivers at California is exactly what NASCAR officials want to see on the track.

"What they did, notwithstanding that Denny got injured, what they did in the last 20 laps is exactly what we would have expected them to do," France said. "This is a contact sport. It's always been a contact sport, especially late in the race.

"They were going at it. It probably didn't hurt the competitiveness that both drivers didn't want the other one to win. They also did want to win themselves. That's how NASCAR racing goes. We won't be having any conversation with them."

NASCAR debuted a new Sprint Cup car this season and France said he was pleased with the racing the Gen-6 has produced so far.

"For all the things that could have gone wrong with the new car and a new season, a lot of good things went really well and we're pleased with that," he told ESPN.
